- Explanation of Basics of Technology
A Wireless Local Area Network, also known as WLAN, Wi-Fi and Airport on
Macintosh computers, makes it possible to set up a local network that connects
computers with ethernet speed without using cables. Via a router computers on this
local network can also communicate with the internet. The technology is relatively
new. It has been experimented with since the mid nineteen nineties. It was
introduced as a standard by the Institute of Electrical and Electronic Engineering
(IEEE) in 1999. The 802.11 standard enabled manufacturers to build hardware that
would be compatible across different platforms in terms of hardware and software.
The most commonly used standard is 802.11b which uses frequencies in the 2.4
Gigahrtz band for the transmission of data and achieves speeds of 2 to 11 Mbits/sec,
which is considerably faster than most peoples internet connections. The technology
was initially conceived for the personal use of individuals and for organisations. It is
licence free, which means that everyone can set up a wireless access point without
having to ask any authority first.

- Free Networking
During the New Economy boom in the late ninetees Wireless got little attention
outside geek communities. At the same time free network enthusiasts started already
to use the technology to build community networks and open access points. This
movement started simultaneously in cities in highly developed industrialized countries
such es the UK, Germany, United States, Australia, Spain...

Most of these initiatives prefer to speak about Free Networks rather than about
Wavelan. Wavelan is just the technology of choice at this point in time, but the free
network idea is the philosophy behind it. Free Networks try to build largely
independent infrastructures for networked communications by interconnecting small
access providers. Their model of growth is based on self-organisation - no single
organisation owns the whole network; each individual node is self-managed by the
user communities who run it; these communities are defined by shared interests and
constituate themselves locally or trans-locally; they promote a supportive and
constructive communication climate within protected online spaces; free networks
are not necessarily free in the sense that no money has to be paid but because of
their autonomy from state institutions and large corporations.
Free Networks found their best expression not with the supposedly global World
Wide Web but with Bulletin Board Systems, in Germany also known as Mailboxes.
Before the WWW became popular BBS's already attracted communities of users in
numbers of tens or hundreds of thousands. Some of them described themselves also
as citizen networks or digital cities. Because their philosophy did not suit the agenda
of the dotcom era their success was overshadowed by the commercial boom around
the WWW. After the crash and facilitated by Wavelan technology free networks are
now having a strong renaissance.
- Trip The Loop
A most basic function that makes wavelan attractive is its ability to trip the local loop.
Failed or unfinished telecommunications privatisation resulted in a market that is still
dominated by the former telephone monopolies. They control the last mile, the cable
that runs into the individual household. This makes permanent internet access in
Europe still relatively expensive and also establishes large telcos and a few mass
market providers such as AOL as gatekeepers who control access to networked
communications also in terms of policiy. They also enjoy a monopoly like situation in
many countries as regards connecting users through ADSL technology, a form of
high-speed internet access that uses standard telephone copper cables. With markets
in a deep recession many high speed networks based on fibre optics are lying unused.
These conditions together have hampered the more democratic use of the internet
and the spread of broadband connections with richer and more interactive audio-
visual services.
With wavelan users who live in geographic proximity can hire together a high-speed
connection to the internet and share the cost, which makes it significantly cheaper.
They also by-pass the controlling ambitions and restrictive policies of large telcos and
access providers.

- Build Community
Wavelan re-introduces locality into networked communications. Setting up an access
point and making it accessible for other people helps to create awareness of who
lives or works in a certain area. The access point becomes a virtual home that
facilitates the creation of services targeted at specific needs of these communities.
This can find many expressions, from ideas for small businesses to very small media
and filesharing applications. Because all computers who use the same node can
communicate with each other on ethernet speed, this is not only fast but can also be
very simple, as simple as opening a section of ones own harddisk for communal use.
Users don't have to pass through the uncertain environment of the internet but remain
within the walled garden of their own network.

- Make a Mesh
Some free networks such as Consume.net in London have wider ambitions than only
the creation of individual Access Points. Consume aims at establishing wireless links
between individual AP's, a wireless meshed network that would cover large parts of
a city. The benefits of community building and associated services which exist within
the user group of one Access Points get extended to a much larger number of
participants who would still remain within one network, by-passing the internet and
forming various interconnected data clouds.
- DIY Power
Many free networks are created in a Do-It-Yourself spirit. Although more and more
packages of commercial hard- and software become available and increasingly
affordable, free networkers prefer to build their own stuff, from router to antenna to
access point configuration. In London this happens with regularly held wavelan
workshops, also called clinics, where wireless enthusiasts, from the interested
newcomer to experienced techie come together to ask questions, share knowledge,
show each other things they have made and discuss what they plan for the future.
The workshops contribute to the social cohesion within wireless communities and
facilitate de-centralized growth of free networks without centralized governance.
Peopel teach each other the How-To's and the What-For's of wireless free
networks.

On Oct. 12th and 13th wireless free networkers met at bootlab Berlin for BERLON,
the Berlin London Wireless Culture Workshop. Practical work on antenna and
nodebuilding and talks about an agreement for wireless free networking were held,
the so called Pico Peering Agreement, which should form the basis for a bottom-up
model of peering agreements between free networks but also define the interface to
commercial providers. With free networkers from Denmark and Spain also present,
this formed an attempt to broaden international collaboration on the basis of the
workshop model.

- War Chalking vs. Cartography
Wireless free networks are a great thing - if you can find them. Recently there was
much media hype about so called war chalking. The idea is that someone walks,
drives or peddalls around with a mobile computer device and tries to find wireless
access points. If one is found a sign is made with chalk on the pavement, whereby
different shapes signify different types of networks, open and closed ones for
instance. The idea was given much media publicity but is almost certainly completely
useless in helping people to actually find access points. Chalk on pavement is washed
a ways quickly by the next rain or street cleaning services. Chalking on walls is
illegal, like graffiti.
More helpful is a number of different ways of wireless cartography. Consume has a
node database, where people who have created an access point can give their
coordinates and a node description, which literally puts them on a map, an interface
for web-investigation on location based information about wireless access points. The
Australian based project nodedb tries to provide mapping services on a worldwide
basis. It links streetmaps with wireless acces points and also information on meshed
networks - wireless connections between access points - and offers node
descriptions in a wiki.

http://www.nodedb.com/unitedstates/ny/newyork/?
These projects have two disadvantages: they depend on users creating their own
entry into a database. This can lead to distortions. For instance, nodedeb has, at the
time of writing no single entry for London, even so there are many nodes on the
consume map. The second problem is that the maps show where access points are,
but not how far the signal that they emit actually goes. This depends on many factors,
such as urban topography, signal strength, type of antenna used.
vortex from free2air.org is working on an advanced research project to overcome
those limits to wireless mapping. He tries to map the actual size and shape of signal
emission from a single node and, with a combination of GPS, geographical
information systems, streetmaps, areal photography and special software, tries to
visualise the real shape of a data cloud, which he calls "air shadow". This type of
cartography gives a much more reliable information about where a signal can actually
be picked up. It also takes out the "war" of mobile mapping, the much hyped "war
driving" as which mobile mapping is usually described in the media, bringing it into
realm of hacker type activities. "air shadow" is a much more useful way of mapping
the electrosphere in an area that could benefit many user groups in different ways
and has nothing to do with "hacking"

- Different Approaches
Different wireless freenets in different cities tend to follow a very different
approach. NYCwireless for instance focusses on providing free public wireless
internet service to mobile users in public spaces throughout the New York City area.
Consume in London focusses more on creating a wireless mesh and promoting free
network ideas of self-management of nodes, knowledge transfer and community
building. Other projects work closely together with public institutions such as local
councils and educational institutions. Wireless projects in rural areas try to attack the
problem that telco providers have failed them alltogether and that only self help will
enable them to get cheap and fast access.

- Commercial Interest
Since about a year or so mainstream media organisations started to report about
wavelan activities, at first mostly on a hostile note, pointing out the vulnerability of
wireless networks for "war driving" hackers. Since then the tone has changed and
wireless community networks got some favourable reporting in media such as The
Guardian, BBC and Der Spiegel. The publicity around grassroots movements of free
networkers has also woken up the industry. Some telco providers and analysts fear
that wavelan undermines 3G, in Germany UMTS technology, the next generation of
mobile phone networks. Providers had to pay huge sums to governments to get a
licence to operate a 3G network. Now they struggle to finance the building of
network infrastructures, while licence free grassroots networks florish. Mobile phone
masts for 3G on nearly every tall building create unprecedent levels of electrosmog
which more and more people fear have effects on health and wellbeing. My personal
opinion about competitive rivalry between wavelan and G3/UMTS is that it does not
really matter. Technologies will become more complementary, combinations of 3G
and wavelan will be built into one and the same mobile devices. More important than
the commercial race is the self-sustained growth of free networks and the
community enhancing applications and services that are being built on their shoulders.
- Parallel (Gift) Economies
Shu Lea Cheangs "Rich Air" project recently conducted in New York presented a
model for the use of wavelan for trading of cultural goods in a money free barter
economy. Inspired by the Argentinian truque clubs, Rich Air illustrates a number of
benefits to be gained from establishing systems that exist outside capitalist markets
and facilitate free exchange in gift economies.

- Conclusions
Free Networks are the antidot to dot-com depression and internet loneliness. They
bring people together in the virtual and the real world, create a buzz and mobilize
fresh energies in people to participate in communal activities. The motivation to do so
is not really altruistic, which is a common misunderstanding. Maybe there will always
be some people who only want to be freeloaders. But for the majority of those
involved in free networking the result is that they get much more out of it than what
they give. As in other gift economies such as free/open slource software
development people benefit from the multiplication of individual efforts. Each one
gives something gets something back from the community at large. On a social and
economic level there are obvious benefits for regeneration in deprived inner city and
rural areas. The existence of wireless access points makes an area more attractive
and, in connection with imaginative projects in cartography and application building,
will develop new business ideas, social and cultural projects. The future of wireless
free networks can not be foretold but so far their potential has hardly been tapped
into.
